BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 294,443, dated. March 4,1884.

Application filedV July 3, 1883. (Xo model.) i i To @ZZ w/wm it may concern:

Be it known that I,'GEO.RGE D. COREY, of Lowell. in the county of Middlesex and State of Massachusetts, have invented a new and useful Improvement in Bottle-Stoppers, of

which the following is a specification.

My improvement relates to bottle-Stoppers vfor closing the mouths of bottles and other similar receptacles; and it consists in certain improvements upon the bottle-stopper patented to M. J. Hinden in Patent No. 175,981, substantially as hereinafter described.

In the drawings, Figure l represents a vertical section of a bottle neck and mouth provided with my invention, and having the stopper secured upon the mouth of the bottle. Fig. 2 represents the same with the stopper raised from the mouth of the bottle. l Fig. 3 is a top view of Fig. l. Fig. 4 is a top view of Fig. 2.

A is the bottle-neck. B is the bail of the stopper, which is secured to a band, C, passing` around the neck of thebottle, and having coils c bent in it, into which the ends of the bail B are sprung in the usual manner, as shown. .On top of the stopper D is secured a metal plate, d2, which has ears upon each side of it, and holes d3 in theears, through which the bail-wire passes to attach the stopper to the bail. These holes permit the stopper and plate d2 to slide freely up and down the bail'- wire suffi cientl y to cork and uncork the bottle, and they are further important in holding the ends of the bail-wire into the coil c as the pressure is brought down upon ythe stopper, thus enabling the use of a more cheap and convenient attachment of the bail to the bottle. This is because Athe holes Vd3 in the ears entirely surround the bail-wire. D is the bottle-stopper, which is formed with a ange, d, which overlaps the mouth of the bottle, and presses down upon its upper face when the stopper closes it. Attachedto the stopper and plate d2 is a verticalpin, e, which projects upward a short distance above the plate. Pivoted upon this pin is a disk E of metal, so as toturn freely around it. This disk E has a slot, e2, channeled or out across it and passing across its axis, of sufficientwidth to allowthe 5o bail-wire B to descend to its bottom. The

pivot e, on which the disk revolves, onl y comes up to the bottom of this slot. Attached to the disk E on one side is athumb-piece, e3, which projects out horizontally sufficiently to enable the disk to be revolved by pressing upon it. 5 5

As will be noticed, this thumb-piece projects radially from the side of. the disk close to one end of the slot e2. At the end of the slot next this thumb-piece the wall of the opposite side of the slot is made cam-shaped, as shown in 6o Fig. l, while at the other end of the slot the wall on the same side of it as the thumb-piece is made cam-shaped in like manner, as shown in Fig. 2. This cam-shape of the opposite'side's of the slot at its opposite ends extends to the 6 5 bottom of the slot and furnishes the means of Yclosing the bottle tightly, as hereinafter deofthe stopper is seated on the mouth of the bottle. In this position the horizontal part of the bail will still remain in the slot e, the 8d length of the bail being so adj usted that it cannot quite come out of the slot. The bottlestopper D and its shoulder d are made of indiarubber or other suitable elastic material; and

it consists of a nose-piece, whichenters and fits the bottle-neck as well as the shoulder d, that rests on top of the neck. rIlhis nose-piece serves to aid in holding the stopple more steadily against the force applied to the thumbpiece e3 in stopping and unstopping the bottle, 9o and prevents the plate d2 from binding upon the bail B. Thile in the position last described, pressure is applied to the thumb-piece e, and the disk E is'revolved in the direction This brings the cam-shaped sides of the slot e2 to bear under the horizontal part of the bail on opposite sides of the disk, and the stopper D and its shoulder d yielding under the compression thus produced, the continued rotation of the roo disk carries its thumb-piece and slot into the position shown in Figs. 1 and 3, and conipresses the stopper tightly upon and into the mouth of the bottle, the bail resting upon the horizontal upper surface of the disk beyond the cani-shaped sides of the slot, which horizontal surface prevents the bottle from being u-nstopped until the disk is revolved backward, s0 as to bring the slot c2 under the bail-wire. The position of the thuinbpiece c is such with relation to the bail-wire that the latter serves to stop it at the proper points on opposite sides of the bail to completely and perfectly stop and unstop the bottle-mouth without any care or attention on the part of the operator. The bail B, being pivoted in the band C, which passes around the neck of the bottle, can be swung entirely out of the way of the bottlemouth when the stopper is raised, as shown in Figs 2 and 4.

The advantages of my improved bottle-stopper are that it furnishes very gr'eat power to compress the stopper upon the mouth ol' the bottle; that all its parts are securely attached to the bail, and the latter to the wireband around the bottle-neck; that it can be operated witout the exercise of special skill on the part of the operator, and that it is simple and not liable to get out of order.

Vhat I claim as new and of my invention The combination ofthe rotating disk E, having slot e2, with cam-shaped walls, the plate di, having holes d d, surrounding the bail-wire, and the bail B, having its ends sprung into holes in neek-band C, with the latter, substan tially as described.
